• the specific name of each functional module is only intended for being distinguished from each other, and does not limit the scope of protection for the current disclosure.
• one or more or all of the steps in each of the exemplary methods herein can be accomplished using a program/software to instruct related hardware.
• Such program/software can be stored in a computer readable storage medium including, e.g., ROM/RAM, magnetic disk, optical disk, etc.
• a user can input multiple touch gestures, which can form many different sequences of trajectories for device verification via various permutations and combinations. Therefore, compared with existing slide -to -unlock technology, device security can be improved. Further, compared with existing methods for inputting passwords, device verification by multiple sliding gestures according to various disclosed embodiments can be conveniently operated and less prone to errors.
